Abstract

What environmental factors are associated with individual differences in political ideology, and do such associations change over time? We examine whether reductions in pathogen prevalence in U.S. states over the past 60 years are associated with reduced associations between parasite stress and conservatism. We report a positive association between infection levels and conservative ideology in the United States during the 1960s and 1970s. However, this correlation reduces from the 1980s onwards. These results suggest that the ecological influence of infectious diseases may be larger for older people who grew up (or whose parents grew up) during earlier time periods. We test this hypothesis by analyzing the political affiliation of 45,000 Facebook users, and find a positive association between self-reported political affiliation and regional pathogen stress for older (>40 years) but not younger individuals. It is concluded that the influence of environmental pathogen stress on ideology may have reduced over time.

政治态度与疾病威胁:区域病原体压力仅与老年人的保守思想有关。
哪些环境因素与政治意识形态的个体差异有关,这种关联是否会随着时间的推移而改变?我们研究了过去 60 年间美国各州病原体流行率的降低是否与寄生虫压力和保守主义之间的关联降低有关。我们报告说,在 20 世纪 60 年代和 70 年代,美国的感染水平与保守意识形态之间存在正相关。然而,从 20 世纪 80 年代开始,这种相关性降低。这些结果表明,对于在较早时期长大(或其父母在较早时期长大)的老年人来说,传染病的生态影响可能更大。我们通过分析 45,000 名 Facebook 用户的政治倾向来验证这一假设,结果发现,对于年龄较大(大于 40 岁)的人来说,自我报告的政治倾向与地区病原体压力之间存在正相关,而对于年龄较小的人则没有。结论是,环境病原体压力对意识形态的影响可能随着时间的推移而减弱。
